those of you that have done the riff diff breather mod and used a fuel filter type filter at the top of your hose , have you experinced any problems ?
im getting ready to do this mod and want to d oit right the first time .
also , the fitting that goes into the diff, has any one found a proper thread size for this ? is it a metric size or sae ? if it is metric , i think ive got the perfect thing , for those of you that have paintballed before , youll know what im thinking , paintball guns that use quick connects have a threaded nipple type male connecter , i jsut happen to have a few laying around and might see if they fit properly . and the cool thing is they have swivel type ones too , so the front diff might be even easier , but they also have 45 degree ones and 90 degree ones.

I am using a Fram G3 (the only Fram item you will find on my rig) filter at the end of the hose and I have had no problems with it.

Several just go to a hardware store and pick up a fitting that goes into the diff housing.
Roger Brown has some info here on that type of fitting.

I could not find it, and low & behold Roger has installed a search engine on his site.
Way coooooool, makes it easy to look up something.
